tions provided with demountable rims.' ItY is the cbj ect ofthe invention /to obtain a construction in which the anchorage or clampingconnection for the demountable rim is engaged directly with the spoke of the wheel, and'it is a further object to bring the points of bearing for the demountable rim in radial alinement with the spokes.y `With these objects in viewgthe yinvention comprises the construction as hereinafter set forth.

In the drawings: A

Figure 'l is an elevation showing` a portion of a metallic vehicle wheel to which my improvements are applied;

Fig. 2 is a cross section in the plane of one of the spokes to which the clamping bolt is secured;

Fig. 3 is a similar view in the plane of an intermediate spoke showing the supporting bearing for the demountable rim; and

Fig. 4 is a plan view of asection of the :rim showing in dotted lines the spoke and securing plate therefor.

In the present state ofthe art metallic vehicle wheels, have been formed in which a center or spider section is formed of two mountable rims have usually been heretofore applied to wheels having wooden fellies, and the clamping bolts for securing these rims have been arranged in the fellies at points intermediate of adjacent spokes. bearings which form the supports for the demountable rim upon the felly have in a certain type of construction been arranged at .distributed points, about the folly. said points being also intermediate of the spokes. With the present construction a demountable Also the rrim is applied to a metallic wheel and is secured by'bolts directly engaging the spokes, which latter are reinforced as hereinafter set forth. l

In detail, .A is the metallic spider section having the hollow taperingspokes/B B etc.

C is a metallic rim which 1s secured to the ends of the spokes B CB by fianged fittings D having ni ple portions E for surrounding the spoke, t e anges being spot-welded or otherwise secured to-the. rim. F is a demountable rim.I lone edge of which is supported upon an inclined flange G of the permanent rim, While'the opposite edge is supported by detachable wedges H secured by. clamping bolts I.

Inasmuch as the wheel is provided with a metallic permanent rim in place of a wooden felly, it is impossible to engage the clamping bolts I intermediate of the spokes` without *the provision of special fittings. To avoid this expense I have so constructed the spokes that the bolts I maybe directly engaged therewith. This I have accomplished by placing within the endV portions of several which engages a corresponding tapering seat in the aperture in the plug.

As the number of clamping bolts is less i than the number 'of bearings required for radially supporting the demountable rim a certain number of intermediate spokes, preferably each alternate spoke, are arranged in alinement with tapering bearings K secured to the demountable rim. and the arrangement is such that when the demuntable rim is in place it will be radiallv supported in A alinement with the spokes. Thus in use, the shocks to which the tire on the wheell is subjectedwill be transmitted directly to the spokes instead of through the laterally-extending portion of the felly, as`with the wooden wheels. l

.What I claim as my invention isz- 1. In a metallic wheel, hollow, thin-walled radial spokes,y a continuous ixed rim vintegrally joinedto and with the outer ends of the spokes, alternate spokes being filled at their outergends and provided through said vfillings with transverse openings adapted edA openings adapted to receive bolts for clamping a demountable rim upon the wheel,

said fixed rim being provided with a rimreceiving abutment at one side.l

3. In a metallic wheel of the bolted-on de mountable rim type, a metallic wheel proper having thin-walled hollow spokes, and a fixed rimowelded to and upon the outer ends of the spokes, eachof said spokes having an outwardly-,extending circumferential flange at its outer end strengthening the spokeand the joint;- between the spoke and fixed rim and some of' said spokes having transverse holes at their outer ends for receiving rimclamping bolts.

4. An automobile wheel comprising a metallic wheel proper having hollow spokes, and a metallic fixed rim upon the outer ends of the spokes and welded thereto, each alternate spoke being provided with a transverse opening adapted to receive a rim-clamping bolt, said fixed rim being provided at one side with a demountablerim abutment, a

demountable rim seated on said abutment and of an inner diameter providing a circumferential slot between the fixed rim and demountable rim, wedge lugs arranged between the two rims and held in position by `bolts in said bolt holes, and rim supporting projections arranged between the demount- .able rim and the fixed rim and supporting the demountable rim at points adjacent to the outer ends of the alternate spokes.

5. In a metallic wheel of the bolted-on demountable rim type, a metallic hub and a fixedrim, hollow spokes connecting the rim and hub, the spokes being reinforced at their outer ends bv means of circumferential outwardly-extending flanges, and alternate spokes being also internally reinforced at their outer ends and provided with ti'ansverse openings for rim-clamping bolts and extending through said internal reinforcements.

6. In a metallic wheel of the bolted-Onde-l having an outwardly extending circumferential flange at its outer end strengthening the spoke and the joint between the spoke and fixed rim, and some of saidspokes having threaded bolt holes at their outer ends for receiving rim-clamping bolts.

7. 'A rim of the herein described boltedon -type,in combination with'a complementary metallic wheel comprising tubular spokes.l a relatively thin metallic fixe'd rim metallically united with and to the ends of all of the spokes, wedging rim clamps secured uponv the outer ends of some of the spokes, and a rim support or stud in substantial alinement with each ofthe other spokes.

8. A rim of' the herein described bolted-on type, in combination with a metallic wheel having tubular. spokes and acontinuous welded on fixed rim, a, circumferential space being provided between the rim and fixed riin, and rim supports in said space one in alinement with each said spoke. j

9. A metallic vehicle wheel comprising a hub, a metallic fixed rim vand metallic hollow spokes extendingfrom the hub'to the rim, the outer ends of the spokes being welded to and with the rim, some of the spokes being provided with transverse holes for receiving demountable rim clamping bolts, andthe fixed rim being provided with means at one side to support a demountable rim.

10. ln a metallic wheel having hollow metallic spokes, a metallic fixed rim welded to the ends of' all of the spokes, some of the spokes being reinforced at their outer ends and provided with transverse openings adapted to receive rim clamping bolts.

ll. rl'he combination with a wheel having a metallic spider formedwith hollow spokes and a metallic rim secured tothe outer ends of said spokes, of ademountable rim, laterally-extending threaded members for clamping said /demountable rim, and reinforcements 'for' the ends of the spokes constitut-
